10 Claims.

This invention is directed to the provision of work holding vise apparatus. I

The novel features of the invention pertain to a vise apparatus adapted for use in connection with a machine tool such as a drill press, boring machine or the like and arranged to hold work for drilling, boring and other operations.

It is common practice particularly when drilling a work piece on a drill press or the like to clamp the work to the work support or to hold the work on said support in some manner.

When successive work pieces are to be operated on, particularly where a hole is to be in the same location on a plurality of work pieces, it is diflicult and laborious to locate and hold the successive pieces to accomplish the desired results.

According to this invention, the vise apparatus may be set so that successive work pieces may be readily and easily clamped for accomplishing like operations on successive work pieces, all as will later appear.

According to special features or the invention, the vise apparatus is simple in form so as to be readily and easily assembled and therefore economical to manufacture while at the same time it is efficient in operation.

With the foregoing and various other novel features and advantages and other objects of my invention as will become more apparent as the description proceeds, the invention consists in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more particularly pointed out in the claims hereunto annexed and more fully described and referred to in connection with the accompanying drawings wherein:

Fig. 1 is a plan view of vise apparatus embodying the novel features of the invention;

Fig. 2 is a front elevational view of the apparatus shown in Fig. 1;

Fig. 3 is a sectional plan view through the movable jaw of the apparatus on the line 3-3 of Fig. 2;

Fig. 4 is a sectional elevational view on the line 3-4 of Fig. 2; and

Fig. 5 is a fragmentary elevational view showing the jaws in a position different than in Fig. 1.

Referring now to the drawings more in detail, the invention will be fully described.

A support is shown at 2 which may be the table or bed of a machine tool such as a drill press, boring machine or the like.

A clamp bolt 4 is provided which may extend through a hole in the support 2 or it may be located in a 1' slot thereoi. and has a manually engageable bar 6 for turning the bolt. A washer 8 and nut to are on the lower end thereof.

Lower and upper clamp members l2 and it respectively are swingable on the bolt 4 and a hollow spindle i8 is rotatable and slidable between said clamp members.

The parts are arranged so that the clamp member and spindle may swing back and forth as indicated by arrow a, while the spindle may reciprocate relative to the clamp members as indicated-by arrow b may rotate as indicated by arrow 0.

A jaw I8 is fixed to the end of spindle l6 by any suitable means such as a set screw 20 and may be called a fixed jaw.

A jaw 22 is slidable back and forth on the spindle l6 as indicated by arrow d.

Adjacent inner sides of said jaws l8 and 22 are formed to have ledges 24 for supporting a work piece such as W. At least one of the jaws such as i8 is provided with a recess 26, see Fig. 2.

An operating screw 30 extends through the spindle l6 and has on one end an operating handle 32 and a shoulder which abuts an end of said spindle, and has on its opposite end a head 34 which prevents relative reciprocative movements of the screw in the spindle.

A nut 26 carried by the jaw 22 extends through a longitudinal slot 28 provided in the spindle l6 which is in engagement with the screw 30, see Fig. 3.

As the screw is rotated in one direction or the other, the jaw 22 is moved on the spindle l6 towards or away from the jaw 18.

It will be noted that the screw is substantially enclosed so as to be protected against matter which could interfere with the operation thereof.

The jaws I8 and 22 are adapted to be supported by the support 2 as indicated in Figs. 1 and 2. A work piece W may be clamped between the jaws l8 and 22 and with the spindle clamped by means of the members I2 and I4 and screw 4 successive work pieces may be clamped by the jaws so that holes 35 may be drilled therein.

It is possible to accurately locate holes in any number of work pieces.

As hereinafter explained, the jaws may be turned upwardly to the position shown in Fig. 5 and successive work pieces such as W may be accurately operated upon.

The jaws may be moved to any location on the support so as to have a certain relation with the tool such as a drill or the like and when fixed in a position one work piece after another may be operated on with accuracy.

The clamp members are arranged to locate the spindle so that its longitudinal axis is parallel with the surface of the support. Opposite longitudinal side faces of the jaws are parallel and end faces of said jaws are at right angles thereto. The axis of the spindle is disposed at a certain distance from the face of the support and the faces of the jaws are spaced from the axis of the spindle a distance corresponding to the certain distance. In this way the jaws may be positioned as in Figs. 2 or 5 and in'either case they are supported by the support.

The invention may be embodied in other specific forms without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all modifications and variations as fall within the meaning-and purview and range-of equivalency of the appended claims are therefore intended to be embraced therein.
